Abstract:
Several prototype systems are described for separating oil and water from emulsions. The systems operate at ultrasonic resonance and are thus low power. Each system contains one or more acoustic transducers operating in the 100 kHz to 5 MHz range. Each system contains flow input for the emulsion and two or more flow outputs for the separated oil and water. Existing prototypes operate from 200 mL/min to >15 L/min. Each uses low power in the range of 1-5 W.

Abstract:
Acoustic perfusion devices for separating biological cells from other material in a fluid medium are disclosed. The devices include an inlet port, an outlet port, and a collection port that are connected to an acoustic chamber. An ultrasonic transducer creates an acoustic standing wave in the acoustic chamber that permits a continuous flow of fluid to be recovered through the collection port while keeping the biological cells within the acoustic chamber to be returned to the bioreactor from which the fluid medium is being drawn.
Abstract:
Systems are provided with varying flow chamber configurations which acoustically agglomerate microorganisms such as algae for separation from a host fluid such as water. Related apparatus, systems, techniques and articles are also described.
Abstract:
Microorganisms such as microalgae are collected and separated from a host medium such as water. Cellular walls and membranes of the microorganisms are then ruptured to release their lipids using a lipid extraction unit. Thereafter, the lipids from the host medium are collected and separated using a lipid collection and separation unit. Related apparatus, systems, techniques and articles are also described.
